Abstract

Precise measurements on conductivity of sodium dodecyl sulphate in presence and in absence of KBr and NaCl in methanol-water mixed solvent media containing 0.1, 0.2 and 0.4 volume fractions of methanol at 308.15K are reported. The concentrations were varied from ~ 0.001 to ~ 0.03 mol.l-1. The results showed a sharp increase in conductivity with increase in concentration of sodium dodecyl sulphate. Also, the conductivity of sodium dodecyl sulphate increases with addition of salts. The conductivity of sodium dodecyl sulphate decreases with increase in amount of methanol. The conductance of sodium dodecyl sulphate is found more in presence of KBr than NaCl in methanol-water mixed solvent media containing 0.1, 0.2 and 0.4 volume fractions of methanol.
